Many PC users work with Microsoft products. For example, with appropriate operating systems. They are called Windows (eng. - "window"). Every year, the development and release of new operating systems. Today, users can enjoy Windows 8 and Windows 10. However, this is not the only software for the computer. There is another highly successful Microsoft product. We are talking about Windows 7. The bulk of users prefer to work with this software. It has a nice and intuitive interface, and also copes with its tasks. But there are exceptions. For example, there are frequent cases in which Windows 7 does not load. How to be What should a user do to bring a computer back to life? Below we will consider the causes of crashes while loading Windows, and also try to figure out how to troubleshoot.
Main reasons
Windows 7 not loading? This operating system is considered one of the most successful at Microsoft. Many users give her preference. But the operating system is highly vulnerable software. Therefore, errors in her work are not ruled out.
Most often, problems with loading the operating system are caused by:
- system failures;
- PC virus infection;
- "cluttered" computer;
- hardware damage;
- improper software installation;
- conflicting components connected to the computer.
In fact, the situation can be corrected in different ways. It all depends on the problem. If Windows 7 does not load, the user will have to find the reason for this behavior (fortunately, it is often easy to do this) and then resolve the conflict. And only occasionally have to agree to extreme measures.
Loading steps
To begin with, we’ll try to understand exactly how the OS loads on the computer. So the user can find out at what stage the problems were identified. This will definitely help in the future.
Today, Windows boots up in 3 steps. Namely:
- OSLoader . The stage that starts with the BIOS launch. That is, immediately after turning on the computer. First, the BIOS code is executed, then the main drivers are connected. They are needed to read data from the hard drive. After that, the Windows kernel and the registry branch are connected.
- MainPathBoot . The biggest download step. It connects to the operating system all the necessary components and drivers. Settings, options, some applications and all built-in services are loaded with MainPathBoot. This stage is displayed on the screen as a blue background, which says "Windows 7".
- PostBoot It is activated when the desktop boots. The stage completes the download of Windows 7, connects the remaining applications and programs.
That's all. In fact, everything is not so difficult to understand as it seems. Nevertheless, you will have to figure out what to do if Windows 7 does not load. Typically, problems are identified at the MainPathBoot stage. But with PostBoot, they also happen. At the OSLoader stage, errors with loading the operating system are almost never encountered. This step lasts only a few seconds.
PC damage
Windows 7 not loading? It is often difficult to understand what exactly happened - a hardware failure or system problems. After all, a computer can behave the same in both cases.
So, if the user thinks that he has damaged some components on the computer, they will need to be replaced. Ideally, take a closer look at the behavior of the operating system. Very often, Microsoft tells the user what the problem is. For example, by displaying the blue screen of death. But more on that later.
After replacing the defective parts, the Windows loading error should disappear. The following situations may indicate a similar problem:
the computer constantly crashes the same driver;
- "blue screens of death" arise;
- OS sounds are heard on the computer, but there is no picture on the screen;
- sudden freezing of the Windows download process;
- computer shutdown during the processing of the stages of loading the OS.
Which of these phenomena and what do they indicate? This will be described below.
Signals - Pointers
An error occurred while downloading Windows 7? Failures are often associated with hardware damage. But what will you have to check first? It all depends on the situation.
Earlier, we cited several indicators of computer hardware damage. But what exactly do they point to? We will try to figure it out.
So, users can focus on the following data:
- driver errors - a malfunction of the device for which one or another software package is installed;
- "blue screen of death" - problems with RAM (but there are exceptions);
- lack of a picture on the screen - damage to the video card;
- OS boot stop - hard drive malfunction ;
- power off during PC startup - there is a problem with the power supply.
Can the listed phenomena occur during the conflict of some components of the computer? Yes. For example, if after installing a new video card the OS does not show a picture on the monitor, either the rest of the hardware should be replaced, or the old “vidyuha” should be returned. Fortunately, diagnosing such phenomena is easier than other problems.
Boot files
Windows 7 doesn’t load normally? Often, users say that they encounter black screens in the early stages of loading. They say "Bootmgr is missing". Further it is offered to press Ctrl + Alt + Del to reboot the OS. Sometimes the user may encounter a normal black screen without any inscriptions. The cursor runs on the monitor when the mouse moves, but nothing more.
This error indicates that the boot file was damaged while the computer was running. Bootmgr is the bootloader for Windows 7 and Windows 8. It is initially hidden from users. Removing it while formatting the hard drive is problematic. Often the cause of the error is viruses.
What to do in this case? Installing Windows 7 on a computer from scratch will help. This is the simplest solution. You can try to restore the operating system, but if this technique does not help, you will have to act decisively and radically.
Registries
Windows 7 not loading? The black screen, as we have said, either indicates a problem with the video card, or underlines the failures of the Windows boot loader. Sometimes when you start the PC does not read and load the registry. This is an extremely important element.
As a rule, an error is detected easily - a corresponding warning appears on the computer screen. In addition, it will be easier to fix the situation than it seems. The computer will launch the recovery wizard. Following his instructions, the user will be able to fix the problem. Not always, but often this technique helps.
Recovery wizard
Only far from always the user will be able to use the automatic recovery wizard of the operating system. Sometimes you have to call it yourself. In addition, if Windows 7 does not load, everyone has the right to use a set of OS recovery tools.
To start the corresponding menu, you must:
- To restart a computer.
- At the boot stage of the PC, press "F8" several times.
- Select "Solve computer problems."
- Enter the access password.
- Click on "Restore Startup".
- After completing the operation, restart the PC.
Using the called menu, you can roll back the system. To do this, just select "System Restore." There is nothing incomprehensible or difficult in this.
Safe mode
Sometimes "Windows 7" does not load only in normal mode. In this case, you will have to restore the OS. It is advisable to do this with the safe boot of Windows 7. In addition, this mode helps to restore drivers and clean the operating system.
To use secure boot, you will need:
- Turn on the computer.
- Press "F8".
- Select "Safe Mode".
You can wait for the operating system to load. Desktop shortcuts on a black background will appear on the screen. To restore the OS, just go to "Start" - "All Programs" - "Standard" - "Utilities" - "Restore".
After a safe boot, the user will be able to use all the services and services of Windows. For example, the command line. It often helps to get rid of some system failures.
Blue death
Sometimes users are worried when loading "Windows 7" blue screen. It is called the "blue screen of death." As we have already said, most often a similar error occurs with problems with RAM.
A blue background appears on the monitor display. It contains certain information about the error in white print. The bulk of the information the user does not need. Just look at the type of error, as well as the "Technical Information" section. With their help, you can understand what’s the matter.
Errors with the hard drive and / or its controller can be indicated by errors of the type:
- stack_inpage_error;
- data_inpage_error;
- inaccessible_boot_device;
- mode_exception_not_handled.
It is advisable to have a handbook of BIOS errors on hand. It contains a complete list of blue screen of death errors. With it, everyone will understand exactly what the Windows 7 download problem is. Installing a new operating system is not required. But how to bring the idea to life?
BIOS reset
Russian "Windows 7" does not load? A similar problem occurs when working with hacked software. By reinstalling it, the error will disappear.
As we said, the blue screen of death indicates damage in the BIOS. Reset situations will help to fix the situation. You can act like this:
- Get to the motherboard and click on the special jumper.
- Remove the round battery and reinsert it. The corresponding item is on the motherboard. It is recommended to completely replace the battery on the PC in case of "BIOS" malfunctions.
- Turn on the computer, press the BIOS call button ("F2", "F4", "Del", and so on - it all depends on the motherboard). Go to Exit and set the pointer to Load Setup Defaults, click on the "Enter" button. Save changes.
Done! Now the "screen of death" will no longer bother the user. But what if the operating system still does not boot.
File recovery
In some cases, Windows 7 does not load due to corruption of system files. They can be restored manually. This technique works if automatic recovery fails.
For manual operation, the user must:
- Run the command line in "Windows 7". It is advisable to do this in safe mode.
- Write: sfc / scannow / offbootdir = c: \ / offwindir = c: \ Windows.
- Press "Enter".
You can wait for the computer to scan and restore the boot files. Usually an operation takes a few minutes.
Recreating a section
Windows 7 loading slowly? What if in the end this operating system did not start?
All the tips listed above did not help? Then you can try to recreate the boot sector. It is also recommended that you rewrite the boot code.
It is done like this:
- Open the command line in safe mode on the computer.
- First enter bcdboot.exe C: \ Windows and perform the operation.
- Write bootrec / fixnbr and bootrec / fixboot.
- Run queries.
- To restart a computer.
Done! Now is the time to check the loading of the operating system. It is possible that the problem will disappear.
Slow work
Windows 7 loading slowly? If the operating system basically works, the user can be offered the following acceleration methods:
- disable startup programs;
- scan the OS for viruses and delete all malicious files;
- run CCleaner and clean the PC registry;
- clean the operating system from files and programs.
All of this really helps. If the techniques were not effective, you will have to agree to reinstall Windows 7. Usually, an installation disk is required for the idea. In the BIOS, you need to put the hard drive first in the Boot section, and then, following the on-screen instructions, complete the installation.
